Gio was named along with A-Rod, Melky Cabrera, Nelson Cruz, and of course Bartolo Colon as allegedly taking PEDs at a clinic in South Florida. Here is the bit on Gio:
There's also the curious case of Gio Gonzalez, the 27-year-old, Hialeah-native, left-handed hurler who won 21 games last year for the Washington Nationals. Gonzalez's name appears five times in Bosch's notebooks, including a specific note in the 2012 book reading, "Order 1.c.1 with Zinc/MIC/... and Aminorip. For Gio and charge $1,000." (Aminorip is a muscle-building protein.)
Gonzalez's father, Max, also appears on Bosch's client lists and is often listed in conjunction with the pitcher. But reached by phone, the Hialeah resident insists his son has had no contact with Bosch.
"My son works very, very hard, and he's as clean as apple pie," the elder Gonzalez says. "I went to Tony because I needed to lose weight. A friend recommended him, and he did great work for me. But that's it. He never met my son. Never. And if I knew he was doing these things with steroids, do you think I'd be dumb enough to go there?"
Hopefully Gio's dad is telling the truth here, and obviously I hope Gio is clean. If not, :(

UPDATE: As our esteemed colleague Jack Kogod points out, NONE of the ingredients in AminoRip are on the MLB’s banned substances list, nor is Zinc and MIC (Methionine, Inositol, Choline).
